To all whom it may concern:

Be it lmown that I, HUGH H. MCGOVERN, a citizen of the United States, residing at Oak Grove, in the county of Clackamas and State of Oregon, have invented certain new and useful Improvements in Ore-Separators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements -in oreseparators and has relation members are capable of adjustment one relatively to the other.

The invention consists in the details of construction, and in the combination and arrangement of the several parts whereby s-certain important advantages are attained scribe the same with reference to the acand the device is rendered simpler, less expensiveand otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel featui'es of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to decompanying drawings, wherein Figure 1 is a longitudinal vertical section taken through an ore separator constructed in accordance with an embodiment of my invention; and Fig. 2 is an enlarged fragmentary vertical sectional view illustrating in detail the separating members or bowls. Fig. 3 is a fragmentary sectional view illustrating in detail certain features of the invention as herein embodied.

As disclosed in the accompanying drawings,'1 denotes a suitable foundation, from which is directed upwardly a suitable hearing 2, in which is rotatably mounted the shfifi 3, ad pted f9! rotation around 8. V?!

tical axis and suitably secured to the upper extremity of the shaft 3, is a disk 4:, of predetermined dimensions and with which is adapted to co-act the adju'stable driving disk 5, driven in any manner which will best suit the requirements of practice.

' this means, it will be readily perceived that the rotation of the disk 4 may be controlled as best suits the purpose.

Suitably secured to the upper surface of the disk 4 is 'the flared extremity 6 of the outer separating member or bowl 7, the.

upper or enlarged end whereof being provided with the outwardly disposed flange 8, whereby an inner separating member or bowl 9 may be adjustably supported relativelyto the member 7. The member 9 is .insertible within the member 7 and has its lower end terminating in blose proximity to the upper face of the disk 4, while the 0pposite'extremity thereof projects above the upper end of the member 7 and is provided with-anoutwardly disposed flange 10 adapted to overlie the flange 8, so that said flanges 8 and 10 may have co-acting therewith the threaded members 11 adapted to be engaged by the conventional nuts or burs 12, whereby it will be readily perceived that the inner member or bowl 9 may be adjusted relatively to the outer member or bowl 7, with convenience and facility. It is also to be observed that the inner member or bowl 9 is of such a transverse diameter relatively to the member 7 as to afford therebetween a passage-way P.

In practice, I find it'of advantage to haye each cofthe members 7 and 9 circular in cross section and to the lower end of the inner member or bowl 9, I suitably secure the annular flat ring or member 14 which projects inwardly thereof and which lies in roj ecting up- 'be'collected or concentrated upon the lining 15 and the tailings discharged over the upper edges. ofthe members or bowls 7 and 9 and as herein disclosed such tailings are received within a housing surrounding the upper portions of the members or bowls 7 and 9 and provided with a downwardly inclined outlet chute 21 through which the tailings are adapted to be discharged.

As the particular form of conveyer 20 forms no part of my present invention, other than its coaction with the bowls 7 and 9, it is not believed that a detailed description thereof is necessary, other than to state that I find in practice to have such conveyer comprise aplurality of spaced rods 22, in such spaced relation asto prevent the passage therethrough of particles over threeeighths of an inch in diameter. I also find it of advantage in practice to dispose intermediate the conveyer 20 and the upper ends of the bowls 7 and 9 the screen '23 which may be of any ordinary or preferred construction. I also find it of advantage to have terminating a predetermined distance above the conveyor 20, so as to discharge thereover and through the screen 23, within the bowls 7 and 9, a conduit 24, leading from any suitable source of water-supply.

In operation it will be perceived that the ore ato be separated is delivered from the;

conveyer 2.0 into the hopper; 18 from which it is dischailged upon the disk 4 and the resultant centrifugal action due to the rotation of the disk 4 will cause the ore to travel over the inner surfaces of the bowls 7 and 9, the metal adhering to the carpets 15 while the tailings are discharged over the, upper edges of the bowls 7 and 9 and collected within .the silrrounding housing and from which said tailings are discharged through the chute 21. By this arrangement it will be seen that the ore to be separated 1S sub-divided and each portion sent over a I single collecting surface.

' From the foregoing description, it is thought to be obvious that an ore separator constructed in accordance with my invention .is of an extremelysimple and comparatively inexpensive nature and is particularly well adapted for use by reason of the cfinvcnienceJandfacility with which it may be assembledfand it will also be obvious that my invention is susceptible of some change and modification without material invention,

nested within the first In tioned bowl and separated therefrom, th bottom of said inner bowl being substantially open, each of said bowls being provided with a surface adapted to retain values, said bowls being relatively-so positioned as to sub-divide the pulp and each adapted to separately concentrate its respective portion, and means coacting with the upper extremities of the bowls for maintaining the inner bowlin operative position.

2. A centrifugal ore separator comprising a body mounted for axial rotation, a bowl secured to said body, and a second bowl nested within the first mentioned bowl and separated therefrom, the bottom of said inner bowl being substantially open, each of said boWls being provided with a surface adapted/to retain values said bowls being relatively so positioned as to sub-divide the pulp and each adapted to separately concentrate its respective portion, and adjustable means connecting the upper extremities of the bowls whereby the inner bowl is maintained in operative position.

a body mounted for axial rotation,;a bowl "secured to said body, and a second bowl nested within the first mentioned bowl and separted therefrom, the bottom of said inner bowl being substantially open, each of said bowls being providedwith a surface adapted to retain values, said bowls being relatively so positioned as to sub-divide the pulp and each adapted to separately concentrate its respective portion, the upper extremities of said bowls being provided with overlying flanges, and means coacting with said flanges for maintaining the inner bowl in operative position.

4. A centrifugal ore separator comprising a body mounted for axial rotation, a bowl secured to said body, and a second bowl nested within the first mentioned bowl and separted therefrom, the bottom of said inner bowl being substantially open, each of said bowls being provided with a surface adapted to retain values,- said bowls being relatively so positioned as to sub-divide the pulp andeach adapted to separately concentrate its respective portion, the. upper extremities of said bowls being provided with overlying flanges, and adjustable means coacting with said flanges for maintaining the inner bowl in operative position.
